y To all whom t may concern.'

Beit known that I, JOSEPH HARRIS, a citizen of the United States, residing at Chicago, in the county of Cook Vand State of..

Illinois; have invented a certain new and useful Improvement in Railway-Car Draft- Riggings, of which the following is a full,

clear, concise, and exact description, reference being had to the accompanying drawings, forming a partof this specification.

rl`his invention relates to improvements in railway car draft riggings.'

Objects of the invention are to provide a draft rigging employing a minimum number of parts and of minimum cost; to provide a structure wherein a yoke or Iyoke acting member is arranged not only to compress the gear proper under draft but to prevent rearward movement of the rear follower of the gear' under bud to provide a stationary member which acts both as a front stop under draft and also as a rear stop for the rear follower'through the intermediary of the yoke under buff to provide an arrangement whereby the parts may be readily applied and taken off the car.

ln the drawing forming a part ofjthis specification, Figure 1 is a vertical sectional view of one form of draft rigging embodying my improvements, the draw* bar and yoke being shown in side elevation. Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. land Fig. 3 is a vertical sectional view taken substantially on the line 2%3 of Fig. 1.

rIn said drawings 10-10 denote the center or draft sills, which are or may be of any.

suitable form, and as show ,the same comprise outwardly turned channels. Secured to said sills is a hollow box-like member j which l designate bythe reference A and,

as shown, the member A comprises an inverted U shaped casting 11 riveted or otherwise suitably secured to the sills along either leg thereof, and a horizontal removable key 12,-'the key 12 passing through alined slots provided in the lower 'portions'of the legs of the U-shaped-member 11 and in the sills. The lower portions of the casting 11 are widened as indicated at 13 to compensate for the metal removed and forming the slots to receive the key 12.

As clearly shown in Fig. 1, the front edge 14 of the horizontal wall 15 and front edge 16 of the key `12 are in vertical alinement.

These edges 14 and 16 form shoulders or abutments or stops for outwardly turned shoulders 17-17 formed on the free ends of' a better bearing for a rear follower 21. The

free-ends of the arms of the yoke 18 are also provided with inwardly turned shoulders or gibs 22-22 which engage and coperate with the upper and lower shoulders 23 formed on the draw bar 24: and, for strength, the free ends of the arms of the yoke may also be provided with side wings or flanges 25 which overlap the sides of the draw bar. A front follower is indicated at 26 and 27 denotes a saddle or tie plate bolted to the sills and adapted to support the yokel and gear proper therewithin.

The -operation is as follows: Upon forward movement of the draw bar, the shoulders 23 thereon engage the shoulders 22 on the yoke arms and consequently pull the yoke 18 forwardly, thus moving the rear.

follower 21 toward the front follower. 26, which latter engages the rear vertical edges 2S of the casting 11 so that the gear proper (not illustrated) between the followers is compressed. Upon rearward or buing movement of the draw bar, the yoke 18 s prevented from rearward movement due to the engagement of theshoulders 17 thereof compress the gear between it and the rear follower 21. In assembling the parts, the

draw bar butt may beflrst inserted between the ends of the yoke arms then the followers and gear inserted in the yokea'fter which these parts may be lifted up between theI sills and secured by inserting the key 12 and attaching thesaddle plate 27. In disassembling, the reverse of the above described operations may be employed or the draw bar may be disconnected from the yoke without taking down the gear by first removing the key 12 and then springing the arms of the yoke sufficient-ly for the shoulders 23 of the draw bar to pass thereby.

I have herein described `and shown one form of my improvements but I am aware roo ` that various. changes and modifications may 'be made in the arrangements and details o f the parts without departing from the spirit of the invention and I contemplate' all such changes andY modifications as come within the `terms ofthe claims appended hereto and in this connection I wish it understood that where I use the terms yoker and follower I do not intend Vto be confined to the exact structures shown in the` drawing, but contemplate any members which act like or v have the function of yokes and followers. It is also obvious that the invention is not necessarily confined to a draft rigging employing a vertical yokeV and that any type of gear, spring or friction may be employed.

I claim l. In a draft rigging for railway cars, the combination with draft members, 4of a draw bar having shoulders, a yoke, each arm of which is'provided with inwardly andout- -wardly turned shoulders, and lstationary means mounted on'the sills adapted'to engage the .'outturned shoulders of said yoke and preventing the latter from moving rea-rwardly, said means also acting as front stops for a, front follower, said inturned shoulders of the yoke engaging' the shoulders'of the draw bar under draft. l

U-shaped member secured to the inner sides of said sills, a transversely extending removable key mounted in slots in said sills, a l U-shaped yoke having the free ends thereof slidable `between the upper wall of said U- shaped member and said key, a drawbar, means operatively connecting the yoke with the draw bar upon forward movement of the ranged to engage the upper wall of said U- shaped member and said key to prevent rearward movement of the yoke under bu.

I 2. In a draft rigging Ifor railway cars, the y combination with centervsills, of an inverted latter, and integral means onthe yoke ar` nieaoee 3. In a draft rigging for railway cars, the combination with center sills, of an inverted U-shaped casting secured to the inner sides of `said sills, a horizontal removable key with said key. 55

4. In a draft rigging for railway cars, the combination with draft members, of upper and lower stationary members extending horizontally between said draft members, a i draw bar having shoulders, and a yoke, the ends of the arms of said yoke being T- shaped and-arranged to have the outer portions thereof engage said horizontal mem- .bers and the inner portions engage said draw. bar shoulders, whereby the yoke and draw bar are movabletogether under draft and the yoke held stationary under buif.

5. lIna draft rigging for railway cars, the combination with draft members, of upper and lower stationary members extending horlzontally between said draft members, a

drawbar the butt of which is positioned between said members, a vertical yoke having the free endsof the arms thereof extending between said upper and lower members and the drawbar butt, means operatively connecting the yoke with the drawbar upon forward movement of the latter, and integral means on said yoke arranged to engage said upper and lower members to thereby prevent rearward movement of the yoke under bud'.
